I recently updated my AT&T Samsung blackjac (1) to windows mobile 6. After doing so, I lost the ability to tether the phone to my laptop to use it to connect to he web. Well, I finally had a genius though breakthrough. I realized that I probably needed to update the AT&T connection manager software. I previously had version 6.3.xx and I just upgraded to 6.7.24.0. Low and behold, this fixed my issue. I can now use the phone to get web access. I hope this helps allyou road warriors out there!
